ATPase Pi (ATPase Assay)

Product description
|
The ATPase Pi is used to determine the enzymatic activity of e.g. myosins, S1, HMM and actomyosin, by measuring the inorganic phosphate released upon ATP-hydrolysis
The ATPase Pi assay is ideally suited to determine the ATPase activity myosins and its proteolytic fragments, as it is reliably easy-to-handle due to its moderate sensitivity range (50µM-1mM inorganic phosphate). Highly sensitive determination methods are usually too sensitive to give precise and reliable results for these proteins. ATPase Pi is a modified assay based on the method of Fiske & Subbarow, where a bluish phosphomolybdate complex forms under reducing conditions. Since organic phosphates remain unrecognized, the assay is suited for phosphoproteins and nucleotides.
